Fully dimensional matched with original Montabert BRP95-LOW / BRH125 hydraulic breakers, corresponds to OEM part numbers 86633963 and 86265741. Direct installation without cutting, grinding or any modification.
Core diaphragm adopts high-elastic PPDI raw material, leather cup uses reinforced HNBR elastomer. Excellent nitrogen isolation, hydraulic oil corrosion resistance, anti-aging and anti-fatigue performance, stable long-term operation under -35°C ~ 150°C alternating temperature.
All finished products pass 130MPa ultra-high pressure fatigue impact test. Effectively prevent nitrogen leakage, maintain stable accumulator pressure, guarantee consistent striking power and avoid frequent weak hammer failure.
Integrates all diaphragm and leather cup sealing accessories required for accumulator full maintenance. One set meets full repair demand, shortens on-site maintenance time and reduces equipment downtime cost.
Every diaphragm and cup seal undergoes air tightness, high-frequency impact aging and oil soaking tests before delivery. Fully meets OEM production standards, delivers stable long-term performance for heavy construction working conditions.
Suitable for Montabert BRP95-LOW / BRH125 hydraulic breakers equipped on multiple heavy-duty equipment:
